A method of measuring the characteristics of a transformer comprises the stepsof determining the transformer turns ratio,switching the load tap changer from the current tap position to a subsequent tap position while determining a primary current and measuring the secondary voltage across the secondary side,determining the primary voltage across the primary side,and determining the characteristics of the transformer based on the determined transformer turns ratio, the determined primary current and the measured secondary voltage.Thereby, the static and dynamic characteristics of the transformer including a load tap changer can be determined. |
